BUILDERS PORTABLE HOT-WATER HEATER.

Application filed January 7, 1916.

To (all whom it may concern.-

Be it'known that I, CHRISTIAN A. LON- DELIUS, Jr., a citizen of theUnited States, and a resident of Chicago, county of Cook, and State ofIllinois, have invented certain new and useful Improvements in BuildersPortable Hot-Water Heaters, of which the following is declared to be afull, clear, and exact description.

This invention relates to improvements in builders portable hot waterheaters and its primary object is to provide a novel hot water heater,capable of being placed in or about an unfinished building during thecourse of its erection, and connected with the water supply of thebuilding.

It is well known to those skilled in the art to which this inventionpertains that during the cold weather it is necessary to heat'water foruse in mixing concrete, cement and the like, and many attempts have beenmade to provide a water heater suitable for this purpose.

One of the objects of this invention is to provide a portable hot waterheater, which may be readily carried about and placed at any desiredlocation in the building, and which may be readily emptied of itscontents after the days work is done, so as to avoid danger of the waterfreezing in the heater, when the same is not in use for any length oftime.

With these and other objects in view, this invention consists of theseveral novel features hereinafter set forth, and particularly pointedout in the appended claims.

This invention is clearly illustrated in the accompanying drawing, inwhich Figure 1, is a central, vertical section through a buildersportable hot water heater, embodying a simple form of the saidinvention; Fig. 2, is a plan thereof; Fig. 3, is a horizontal sectiontaken on the line 83 of Fig. l, and Fig. i, is a side elevation of afragment of the hot water circulating system.

Referring to said drawing, the reference numeral 10, designates atubular shell or casing, supported by legs 11, secured to the lower endof said shell or casing in any suitable manner as for instance byrivets. The shell is open at the top and bottom, and its upper end isclosed by a cover 12, that rests upon the top of the shell, said coverhaving a large opening 13, which is covered Specification of LettersPatent.

by a lid, let, hinged to the cover by hinges 15. In the lid 14, is adraft opening 16, for aiding combustion in the fire box or combustionchamber. The large opening 14, furnishes access to the interior of theshell and the fuel may be inserted through said opening. Secured on theinner wall of said shell 10, near its lower edge, is an annular angleiron 17, which furnishes a shelf or ledge for supporting coils of pipe18, through which the water is circulated. Said colls of pipe comprisevertical coils 19, 19 and horizontal pipes 20, connected with the lowerends of said vertical pipes in such a manner as to form a continuouspassage for water extending from one end to the other of the severalcoils of pipe. In the embodiment of the invention illustrated in thedrawings, the pipe 18 is the inlet pipe, and it has extension 21 at itsupper end which leads out over the top of the shell 10, and has ashut-elf valve 22, therein, whereby the supply of water to the coils maybe regulated. The extreme end of the pipe 21, is arranged for connectionwith a hose or other flexible pipe 23, which leads to and is connectedwith the water supply of the building. The pipe 18 is the discharge pipeof the hot water heater and has an upward extension 24, extending up andover the top of the shell, and arranged for connection with a hose orother flexible pipe 25, the end of which may be carried to the pointwhere it is desired to deliver the hot water. The connections betweenthe extensions 21, 24 and hose 23, 25, comprise the usual screw threadedconnections, common and well known to those skilled in this art.

In the embodiment of the invention illustrated herein the lower end ofthe inlet pipe 18 connects with the lower end of a plurality ofconnected vertical coils 19 as illus trated in Fig. 4, and the lower endof the last pipe of said upright coils 19 connects with the first one ofthe horizontal pipes 20, which pipe runs across to a point adjacent theinlet pipe 18 where said horizontal pipe 20 connects with the lower endof an upright pipe of the upright coils 19*. lower ends of each uprightcoil 19 are connected to horizontal pipes 20, which extend across to thelower ends of the upright coils 19, on the opposite side of the heater,so as to form a continuous circulating system The 1 through the uprightand horizontal pipes. The discharge end of the circulating system isformed substantially as is the inlet end whereby a series of verticalpipesare provided, which extend along the inner face of the shell, and aseries of horizontal pipes are provided which extend across the bottomof the shell to act as grate bars for supportingv the fuel in thecombustion chamber thereabove.

In use, the shut-off valve 22, is opened to permit water to flow intoand fill the water circulating system of the hot water heater, afterwhich said shut-0E valve is closed. Fuel is placed in-the combustionchamber and is ignited, and the water is heated thereby. Preferablysuiiicient fuel is placed in the heater to cover the vertical coils ofpipe and inasmuch as coke is usually used as fuel it creates an intenseheat, thereby quickly heating the water contained in the circulatingsystem.

When it is desired to draw hot water, the shut-0E valve 22, is opened,whereby the pressure from the source of water supply forces the waterout of the water circulating system of the heater and discharges itthrough the hose, 25.

At the close of the day, the coils of pipe may be bodily removed fromthe shell, one

of the hose detached from the coil of pipe and the latter may be laidupon its side to drain it of all the water contained therein, thusavoiding any danger. of freezing.

More or less variation of the exact details of construction is possiblewithout departing from the spirit of this invention, and I desire,therefore, not to limit myself to the exact construction shown anddescribed, but intend in the following claims to point out all of theinventions disclosed herein.

I claim as new and desire to secure by Letters Patent:

1. A builders portable water heater, comprising a shell open at the topand bottom, supporting legs therefor arranged to support the open bottomof the shell in an exposed condition free from the object on which theheater stands, a cover for the open top of the shell, a watercirculating coil removably supported in the shell and having a largesurface area, the ends of said coil being arranged for connection withflexible inlet and discharge pipes, said water circulating coil havingclosely spaced pipes arranged close to the inner face of the shell andhaving horizontal closely spaced pipes arranged adjacent the open bottomof the shell, said coil forming the fuel supporting means for the heaterand the entire structure being readily portable.

2. A. builders portable water heater, comprising a shell open at the topand bottom, supporting legs therefor arranged to support the open bottomof the shell in an eX- posed condition free from the object on which theheater stands, a cover for the open top of the shell, a watercirculating coil removably supported in the shell and having a largesurface area, the ends of said coil being arranged for connection withflexible inlet and discharge pipes, and a shut oif valve on one of saidends of the coil, said water circulating coil having closely spacedpipes arranged close to the inner face of the shell and havinghorizontal closely spaced pipes arranged adjacent the open bottom of theshell, said coil forming the fuel supporting means for the heater andthe entire structure being readily portable.
